How to load comtrade data .cfg-.dat

delldev · March 4, 2023, 7:27pm

Hello, I installed the necessary packages with NuGet, but I cannot import the Comtrade files(.dat and .cfg). I tried different ways with .Net and .NetFramework, can anyone give me an example code to open the files for c# winform or windows form app?

Here is a fairly simple example of code that reads from a COMTRADE file using the GSF.COMTRADE library. It just reads the timestamps and values into a collection of ParsedChannel objects to be used for populating a chart.

          using (Parser parser = new Parser())
          {
              parser.Schema = new Schema(configurationFileName);
              parser.FileName = dialog.FileName;
              parser.InferTimeFromSampleRates = true;
          
          
    // Open COMTRADE data files
              parser.OpenFiles();
          
          
    // Parse COMTRADE schema into channels
              m_channels = parser.Schema.AnalogChannels
                  .Select(channel => new ParsedChannel()
                  {
                      Index = channel.Index,
                      Name = ((object)channel.ChannelName != null) ? string.Format("{0} ({1})", channel.StationName, channel.ChannelName) : channel.StationName,
                      TimeValues = new List<DateTime>(),
                      XValues = new List<object>(),
                      YValues = new List<object>()
                  }).ToList();
